DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 and 2 are perspective views of two portable shelters 10 according to the invention. Each shelter 10 includes an insulating, foldable base 12, which serves as a sleeping support for the user. The support base 12 includes a support board portion 13 provided with a sleeping surface 14, which may be of a suitably comfortable pad material to facilitate restful sleep. The support base, which will be described in detail later, preferably includes a plurality of depending foot members 16 to raise the support board portion 13 above the ground or floor surface on which the shelter is placed for use.

A collapsible hood 20 is attached to the support base 12 to cover the user and provide a desired degree of privacy and protection from the elements. The hood 20 may be deployed to provide partial or full coverage of the sleeping surface 14. The hood includes a cover 22 of protective material, such as neoprene, supported at positions R by a plurality of U-shaped support members 24 (shown in FIG. 3 to be discussed later). Each of the support members 24 has its opposite ends pivotally supported to the support base 12. In the form shown in FIG. 1, the support members 24 are situated between layers of cover material, such that they are not exposed. However, one or more of the support members 24 may be exposed on the outside and/or the inside of the cover 22, as desired. An illustrative arrangement is shown in FIG. 2, where the front (left-most) support member is exposed. Otherwise, the shelters of FIGS. 1 and 2 are the same, except for color. The cover 22 may be attached to the support members 24 in any desired manner, such as by tacking, bonding, or forming the cover with channel-like pockets in which the support members 24 are inserted and confined. Other techniques will be readily apparent to those skilled in the art. Support members 24 can be made of plastic, such as PVC, or of any other suitable material, such as aluminum or other metal.

One end of the hood 20 is preferably affixed to the foldable support base 12 to increase stability and to simplify use of the shelter. With the hood 20 fully deployed to provide full coverage of the sleeping surface 14, the user is afforded complete privacy within an enclosed space beneath the hood and is effectively protected from the surrounding environment. The hood 20 may include one or more screened window openings with zippered covers (not shown), which may be open to allow for air flow between the surrounding environment and the space beneath the hood. Partial deployment of the hood as shown in FIGS. 1 and 2 provides partial privacy for the user. The arrow in FIG. 2 indicates that the free end of the hood may be pulled fully forward and downward such that its inner periphery is juxtaposed to the outer periphery of the support board structure 13, thus providing a fully enclosed space.

FIG. 3 illustrates the construction of the foldable support base 12 in more detail. The foldable support base 12 is made of two portions, which are foldably coupled to one another by a hinge 26 (shown in FIG. 4 to be discussed later). In a preferred embodiment the U-shaped support members 24 are also pivotally supported on the hinge, such that the support base 12 and the hood 20 share a common pivot axis to facilitate quick and easy folding and unfolding of the personal shelter for transport and subsequent use.

The two portions of the foldable support base 12 can be constructed as identical U-shaped halves 12 a, and 12 b. Each half of the support base 12 includes a corresponding half of the support board 13 provided with a plurality of foot members 16. Each half of the support board 13 is constructed with a frame portion 30, preferably made of PVC or other suitably strong and lightweight material. The frame portion 30, has a plurality of axially extending internal dividers 31 and a surrounding peripheral wall 31 a between its top and bottom walls 32, 33 to define a plurality of internal spaces 34. Spaces 34 are filled with corresponding inserts 36 preferably rigid foam insulation, such as rigid polystyrene. The thickness of each insert 36 is selected to match the height of dividers 31 and peripheral wall 31 a. In practice, the top wall 32 of the frame portion 30 can be attached or molded to the remainder of the frame portion after installation of inserts 36, followed by attachment of a corresponding half of the comfort pad 14 to the top wall of the finished frame portion. The foot members 16 are conveniently made of the same material as the frame portion, so that the foot members 16 and the frame portion bottom wall, peripheral walls 31 a and dividers 31 can be formed as a single molding.

FIGS. 4A and 4B are diagrammatic top plan and side views, respectively, of the illustrative embodiment of the invention. Sectional views A and B represent cross-sections through the support base at the positions indicated in FIG. 4A. View 4C illustrates a hinge connector 26, which connects the two halves 12 a, 12 b of the foldable support base 12 together and having the U-shaped support members 24 of hood 20 pivotally mounted thereon. The hinge connector 26 may be of any design suitable for attachment to the two halves 12 a, 12 b of the foldable support base 12 to couple the halves together. For example, the plates of the hinge connector may be made of PVC and bonded to the respective halves 12 a, 12 b of the support base 12. As shown in view 4B, the straight end of each support base half may be provided with a recessed portion 38 to receive a corresponding hinge plate, so that the foot members 16 at the center of the assembled support base 12 come into face-to-face engagement, the foot members thus acting as stops which limit unfolding the foldable base 12 to a state in which the sleeping surface portions of the halves 12 a and 12 b are coplanar. View 4D illustrates a support member 24 supporting cover 22 of the hood 20.

FIG. 5 is a series of views illustrating the manner in which the personal shelter 10 of the invention is folded for transport. Basically, the two halves 12 a, 12 b of the foldable support base 12 are folded upwardly about a hinge 26 and brought substantially together, causing the hood 20 to collapse with the cover support members 24 pivoting about hinge 26 and gathering together between the support base halves. The opposite ends of the support base 12 may be provided with straps 40 or other means to secure the ends together to prevent unintended unfolding of the shelter 10. As shown, the foldable support base 12 may also be provided with shoulder straps 42 to permit carriage of the shelter 10 in the manner of a backpack.

In large numbers, the portable shelter 10 of the present invention can be used as an effective means in the battle against homelessness and in situations, such as natural disasters, where mass sheltering of numerous people is required. Many homeless individuals own a shopping cart, which they use to transport their belongings. As shown in FIGS. 6A and 6B, the straps 42 may be used to secure the shelter 10 of the invention to the front end or undercarriage of a shopping cart for transport. When mounted as shown in FIG. 6A, the weight of the shelter is conveniently borne by one foot member 16 resting on the top front edge of the shopping cart basket. The shelter of the invention may also be used for recreational purposes.

It should be understood that the present invention is not limited to the embodiments described herein. Rather, those skilled in the art will appreciate that various changes and modifications can be made in keeping with the principles exemplified by the illustrative embodiments.
